I cut out reading (24 hour) news this year. I no longer read bbc news, my local papers etc. I figured (and it's true) important things tend to get mentioned (either on HN, or just in conversation etc.)
There's also the idea of the "circle of influence" (i.e. worry / do something with the things you can _actually_ influence, forget about the rest - slightly comes back to the 24 hour news thing for me). Perhaps you might enjoy reading "The 7 Habits of Highly effective people"
I did this too, and it feels great. I can't remember where I heard it from but I'm stealing it:
"I would rather be uninformed, than ill-informed"
A lot of what you see on TV and read in newspapers is either advertisements from PR firms disguised as news items or propaganda. This is even more so if it's election season.

Good luck :) You're certainly not alone.
